Use these for BJJ training and competition. Had an old knee injury in my left knee, and a new one in my right. These provide excellent support as well as outstanding cushioning. On my second set of them now. Won't buy anything else as long as these are available.

This product has seal rubber tubes, there are no seams on the inside area of the knee on this pad.
